In an epoch, a certain section may be especially well known because of rich fossil finds. Pakicetus is an extinct genus of cetaceans that lived about 50 million years ago.

Geological evidence of the megadrought at the onset of the Meghalayan can be found on all seven continents. It was first discovered in Pakistan and was named by Philip Gingerich and Donald Russell in 1981. The Antarctic Vostok ice core provided compelling evidence of the nature of climate, and of climate feedbacks, over the past 420,000 years. Pakicetus is a genus of extinct predator mammal which belonged to suborder Achaeoceti. The known geological history of Earth since the Precambrian Time is subdivided into three eras, each of which includes a number of periods. The Department of Geology. New Geological Period. College of Liberal Arts and Sciences. They ate meat, sometimes fish and are the ancestors of whales, porpoises and dolphins. Virtual Field Trip Home. They were also quite small by whale standards, reaching about four-feet in length. These rocks range in age from Permian (as old as 270 million years old) to Cretaceous (as young as 80 million years old.)

It was endemic to the territory of present-day Pakistan. They were mammals and looked like large rodents. The School of Earth, Society, and Environment. Questions? They, in turn, are subdivided into epochs and stage ages. Nearly 10,000 feet of sedimentary strata were deposited in the Capitol Reef area.

It is the most ancient of presently-known direct ancestors of modern-day whales that lived approximately 48 mln years ago and adjusted to searching for food under water. Go to Desktop Site. Straddling the two worlds of land and sea, the wolf-sized animal was a meat eater that sometimes ate fish, according to chemical evidence. About. This prehistoric whale remained semi-aquatic as the modern-day otter. Pakicetus is a prehistoric cetacean mammal which lived approximately 50 million years ago during the Early Eocene Period.

The geologic story of Capitol Reef can be broken down into three steps, each of which occured over millions of years of geologic time: deposition, uplift, and erosion.
